2016 Chevy Cruze is lighter, loaded [UPDATE]

UPDATE: Live photos and video of the reveal have been added at the end of the story. Chevrolet revealed the second-generation Cruze Wednesday, promising a larger, more efficient car that drives better than the sedan it replaces. We're particularly excited about the new turbocharged, 1.4-liter four-cylinder engine, which makes 153 horsepower, an upgrade from the outgoing 1.8-liter naturally aspirated engine's 138 hp. Torque climbs even more significantly, from 148 pound-feet to 177 in the new mill. Peak twist can be called up between 2,000 and 4,000 rpm, which should make performance easy to access. Combined with a lighter architecture that slashes the Cruze's curb weight by 250 pounds (although the actual curb weight hasn't been released), the new four-door can hit 60 miles per hour in a respectable eight seconds. That's not hot hatchback territory, but it should be more than suitable for the average consumer. That same consumer should also appreciate the new engine's economy. The Cruze now returns an even 40 miles per gallon on the highway and will cover 530 miles on a single tank, all the while running on plain old 87-octane fuel. There's also a diesel-powered Cruze model, although Chevy didn't release specific details, aside from saying that it will arrive in dealers in 2017, over a year after the gas-powered model's early 2016 on-sale date. Despite the 250-pound drop in weight, the new Cruze has grown significantly. Its wheelbase is now the longest in the segment, with 106.3 inches of sheetmetal between the front and rear axles compared to 105.7 in last year's model, while the sleek new body cuts the coefficient of drag to just 0.29. The overall length increases from 181 inches to 183.7, though the new model is nearly an inch lower overall. That's both good news and bad news for interior space. Rear legroom is up from 35.4 to 36.1, but headroom is down in both the front and backseats by over half an inch. Tech fans, meanwhile, will appreciate the new standard MyLink display. The seven-inch touchscreen is compatible with both Android Auto and Apple CarPlay, while an optional eight-inch display will be offered, as well. 4G LTE wi-fi, heated rear seats, a heated steering wheel, and wireless phone charging will also be offered as an optional extras. New safety features include blind-spot monitoring with cross-traffic alert, lane keeping assist, and forward collision warning.

Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.

Porsche wins the 2015 24 Hours of Le Mans

The question going into this year's 24 Hours of Le Mans was whether or not the Porsche 919 Hybrid would be able to combine its qualifying pace with race reliability. After battling neck-and-neck with Audi's R18 for most of the race, the answer is a resounding yes. Not only did Porsche drivers climb the first two spots on the podium, they did so without any major mishaps on track. This win is the first overall trophy for Porsche since 1998. Audi previously won the last five races, and 13 of the last 15. Corvette also returned to the winner's circle, with the No. 64 C7.R taking winning the GTE Pro division. The victory is the first class win for Corvette since 2011. KCMG won the LMP2 class in ninth overall. With 45 minutes to go the No. 98 Aston Martin crashed out of first place in GTE Amateur, giving the class win to SMP Racing's Ferrari and second place to the Patrick Dempsey Racing Porsche 911 RSR. For the full list of official results, click here. The GTE Pro class proved to be just as exciting as the P1 class, with a four-way battle for first after four hours into the race. For most of the race, the battle at the top went back and forth between the two German manufacturers. An tire puncture in the No. 7 Audi gave up the lead to Porsche, and moments later a crash forced the No. 8 into the garage. But a three-minute replacement of the front and rear bodywork kept the Audi in contention. As the race wore into the night, Porsche maintained a slightly faster pace than Audi. Nick Tandy took the lead on Lap 253 early Sunday morning, and car No. 19 never gave up the top position. The win is the first for all three drivers of the No. 19 – Nico Hulkenberg, Earl Bamber, and Nick Tandy. A lap behind in second was the No. 17 Porsche. The Audis fought reliability problems late in the race but still finished third with the No. 7 R18. The GTE Pro class proved to be just as exciting as the P1 class, with a four-way battle for first after four hours into the race. As the Aston Martin cars dropped away, the lone Corvette Racing entry took over, followed by a charging AF Corse team Ferrari 458 Italia. The Corvette and Ferrari continued to trade places in the final hours until gearbox trouble forced the No. 51 Ferrari out of contention. It was eventually passed by the other AF Corse car, No. 71. Nissan experienced all the pain of a first-year effort with its front-wheel-drive GT-R LM Nismo.
